Now that Internet Explorer 9 has been let out its cage, we all know a great deal more about Microsoft's position towards the video codec situation with the HTML5 video tag. Microsoft has chosen for H264, a codec it already includes in Windows by default anyway. This means that apart from Firefox and Opera, every other major browser will support H264. Some are seeing this as a reason for Mozilla to give in to their ideals and include support for H264 as well - I say: Mozilla, stick to your ideals. The last people you should be listening to in matters like this are web developers.
